    Power and Mass Question -- A helicopter accelerating and ascending

    okay, I used the power = change in energy/time equation and got this: Ei = 510m Ef = 13580.5m Change in energy = 13070.5m 460000 = 13070.5m/140s 460000 = 93.4m m = 4925.1kg I'm not sure if this is right.

    Power and Mass Question -- A helicopter accelerating and ascending

    I started with calculating the Ep and Ek of the helicopter and got this: Epi = 490m Eki= (1/2)(400m) Epf = 12740m Ekf = (1/2)(1681m) I don't really know where to go from there. Do the unknown mass variables cancel out? I'm lost!
